In 2375, the Regent's flagship was equipped with a cloaking device that was stolen from the IKS Rotarran in the "prime" universe. However, the cloak was sabotaged by Rom during its installation, disabling the entire ship and leaving it vulnerable to attack by the ISS Defiant. The Regent was forced to surrender as a prisoner of war in the engagement. Presumably the Terran rebels salvaged the ship. (DS9: "The Emperor's New Cloak")

The Regent's flagship appeared almost physically identical to the Negh'Var warship, but it was scaled up several times when compared to the other ships in the fleet. The DS9 effects designers built a special thirty-foot-long studio model of the underside of the ship for use in the Defiant's strafing runs, in order to make sure that the two ships appeared properly scaled.
